BASIN-PLUG THIM BLE.

SPECIFICATION forming part of Letters Patent N 0. 605,813, dated June14, 1898.

Q Application filed November 22,1897. Serial No. 659 A24. (No model.)

' To all whom it may concern.-

Be it known that I, FREDERICK S. CHASE,

' of Waterbury, in'the county of New Haven and State of Connecticut,have invented a new Improvement in Basin-Plug Thimbles; and I do herebydeclare the following, when taken in connection with the accompanyingdrawingsand the letters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part ofthis specification, and represent, in a Figure 1, aview in side elevation of a basinmy invention; Fig. 2, a view thereof invertical section showing it coupled to a discharge-pipe; Fig. 3, adetached plan view of the strainer after it has been flattened out; Fig.4, a broken sectional View showing the strainer after its initialintroduction into the basin-plug thimble, but before it has beenflattened out to permanently connect it thereto.

My invention relates to an improvement in Y basin-plug thimbles, theobject being to produce a simple, cheap, and effective article.

With these ends.in view my invention consists in a basin-plug thimblehaving certain details of construction and combinations of parts, aswill be hereinafter described, and

' is formed of sheet metal and provided at its upper end with anoutwardly-turned flange B and having its lower end formed with ex.ternal screw-threads B Preparatory to the introduction of the strainerinto the thimble it is concaved, so as to permit the initial en tranceof its flanges A A into the said overflow-openings B B. When in thisposition, the strainer is flattened, causing its virtualextension,wherebyfits flanges are moved outward into the said openings,as shown in Fig. 2, so that the strainer is as effectually secured inplace as though it were soldered to the thimble, from which it cannot beremoved unless it is concaved or otherwise bent, so as to virtuallyreduce its length and withdraw its flanges from the said openings,which,however, are not occupied or filled up bythe said should be loose itcannot move except withimvery narrow limits, as its flanges cannotb'e,got out of the openings. plug thimble constructed in accordance with Incarrying out my invention I by preference also turn the lower edge ofthe thimble inward to form a bearing-flange 13 which rests upon'thewasher O, which in turn rests upon the outwardly-turned flange D of thedischarge-pipe E, which is coupled to the thimble by means of aninternally-threaded coupling ring F, which engages with the threads Band with the flange D, as shown.

The flange B forms a wide bearing for the washer, and not only increasesthe effectiveness of thejoint between the thimble and discharge=pipe,but also prevents the washer from being cut by the lower edge of thethimble.

I would have it understood that I do not limit myself to the exactconstruction shown and described, but hold myself at liberty to makesuch changes and alterations as fairly fall within the spirit and scopeof my invention. Thus instead of utilizing the overflowopenings for thereception of the strainerflange I might form special openings in thethimble for the said-flanges.

Having fully described my invention, what I claim as new, and desirecure by Letters Patent, is

containing a sheet metal strainer provided with flanges adapted to enterthe said open ings with which they are permanently en-*- gaged byflattening the strainer,which is concaved to permit its initialassemblance with the thimble.
